Abstract
To provide an electrocorrosion preventive rolling bearing assembly wherein a final machining of an electrically insulating layer and a thickness control of the insulating layer can easily and accurately be accomplished, the electrocorrosion preventive rolling bearing assembly is of a type in which an inner race () or an outer race () is formed with an insulating layer () so as to cover a peripheral surface thereof, which engages a housing or a shaft, and opposite annular end faces thereof. The insulating layer () is a thermally sprayed layer of a metallic oxide. Of the inner and outer races () and (), a raceway member having the insulating layer () is provided at its end face with a tool reference plane () for a process of finishing the electrically insulating layer () or for the thickness control of the insulating layer. This tool reference plane () may be either an indented radial surface of a step () formed in the end face or a bare portion of the end face that is left uncovered by the insulating layer ().
